Abstract

The invention provides an electronic gear proportion smooth switching system, which is used for controlling a servo motor to realize smooth switching from an initial electronic gear proportion to a target electronic gear proportion. The electronic gear proportion smooth switching system comprises a numerator adjusting unit, a denominator adjusting unit and an operation control unit, wherein the numerator adjusting unit is used for adjusting the numerator of the initial electronic gear proportion to the numerator of the target electronic gear proportion by one unit; the denominator adjusting unit is used for adjusting the denominator of the initial electronic gear proportion to the denominator of the target electronic gear proportion by one unit; the operation control unit is used for running the servo motor by using the adjusted initial electronic gear proportion; and the numerator adjusting unit, the denominator adjusting unit and the operation control unit are executed once at every scheduling period. The invention further provides a corresponding method. The numerators and denominators of the electronic gear proportions are gradually adjusted respectively, so that the motor running speed can be smoothened effectively, and excessive following deviation failures are not misreported.

Description

technical field [0001] The invention relates to the field of servo motor control, in particular to a system and method for smooth switching of electronic gear ratios. Background technique [0002] The screw is a product that converts rotary motion into linear motion, or converts linear motion into rotary motion, and is currently widely used in various industrial equipment and instruments. By controlling the rotation of the servo motor, the speed and position of the linear motion of the screw can be controlled. For example, when the movement speed of the screw rod changes, the servo motor needs to adjust the electronic gear ratio. [0003] During the real-time switching process of the electronic gear ratio of the servo motor, the position follow-up deviation is calculated through the electronic gear ratio to obtain the position command deviation. When the electronic gear ratio is switched from high to low, the position command deviation becomes larger, and vice versa. If th...
